From very humble beginnings, Dr. Duncan emerged as a shining example of determination and resilience. Despite his parents’ lack of formal education, they instilled in him the values of hard work, honesty, and integrity. Inspired by his blue-collar background, Dr. Duncan embarked on a journey to pursue higher education, fueled by his family’s unwavering support.
To fulfill his dreams of attending college, Dr. Duncan joined the ROTC and dedicated four years of his life to serving as a regular army officer. His dedication and commitment did not go unnoticed, as he was awarded an army scholarship for medical school. Driven by a sense of duty, he then served as a medical doctor in the army for an additional seven years.

Amanda Essert, MSN, ARNP is a board-certified Family Nurse Practitioner with more than 20 years of nursing experience, including 12 years in emergency medicine. Growing up in Tenino, she is a longtime Northwest native with a deep-rooted connection to the community she serves. It was her own life-changing autoimmune diagnosis that inspired the journey to seek a better understanding of health and longevity.
Amanda’s personal experience with polymyositis, a rare autoimmune disease, changed the way she views medicine. Navigating a complex condition firsthand taught her what it feels like to long for real answers and the need for a provider who searches deeper, looking beyond just symptoms. That experience sparked her passion for functional and root-cause medicine, and it continues to shape the compassionate, holistic care she provides today.
Amanda believes healthcare is more than treating illness. It is helping people build healthier, stronger lives through education, personalized care, and a proactive approach to wellness. Her practice centers on a holistic view focusing on metabolic health, hormone management, and disease prevention. Amanda’s mission is simple: help every patient gain more healthy years, more energy, and more freedom to live life on their own terms.
